windows-services

I have a server written in Java that runs as a Windows service (thanks to Install4J). I want this service to be able to download the latest version of the JAR file it runs from, and start running the new code. The stitch is that I don't want the Windows service to fully exit. Ideally, I would accomplish this by a unix-style exec() call to stop the current version and run the new one. How can I best accomplish this? Here is a complicated, but portable, way. Split your code into two jars. One very small jar is there just to manage process startup. It creates a ClassLoader that holds the other

I want to run multiple instances of a window service installed on a server without installing window service again. How is this possible? A service "installation" is really just adding a mapping between a name, an executable, and a few other bits of metadata. A service, once installed, is either running (once), or it isn't. To have multiple instances running as services , they would have to be registered with different names, which basically means installing it multiple times. That does not , however, mean that you need multiple different copies of the executable. The way I do it is to

I'm attempting to build a windows service that's self-hosting SignalR. I have read through tutorials such as SignalR Self-Host on ASP.Net I'm noticing that, least it seems, that they're based around broadcasting messages, and can't seem to find anything around listening. I need to listen to messages from within the service, as well as broadcast. We already have our backplane setup - it's the same one that the site uses. In a web site I can join a group, via Javascript. How do I join a group in a self-hosted SignalR service. In a web site I register a callback on a hub. How do i register the

I have a windows service running on my machine. When I do a Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments) it gives me empty string but when I do the same thing in a console application it gives me the correct location of my MyDocuments folder. Any ideas as to why it might be happening? That is because when you run the application as a Console you are running signed in to the computer as you, the user, and can therefore access your "My Documents". When the Windows Service is running (by default) it will run as Local System which doesn't have a "My Documents" folder.

I have written a simple windows service which will launch a exe specified in the onstart() method of the service. After starting the service the exe got launched it only presents in the memory but it doesnt show in the explorer. I'm trying to launch a calc.exe from my code.it shows the exe in the memory but it doesnt comes into my view(i.e) in the explorer. Below is my code to launch the exe in the onStart() method Process pr=new Process(); pr.StartInfo.FileName="calc.exe"; pr.StartInfo.WindowStyle=ProcessWindowStyle.Maximized; pr.StartInfo.CreateNoWindow=false; pr.Start(); // pr.WaitForExit()

After I installed Windows 8 perfectly legit statement like this doesn't work anymore: #if DEBUG Debugger.Launch(); #endif Service starts ignoring that thing. Yes, I am building the project in a debug mode. if I change that to a Debugger.Break() - the service just fails, and still there's no dialog for attaching a debugger. Debugger.Launch would launch an application with a visual GUI. By default services do not interact with a desktop and thus anything they do cannot be "seen". Support for interacting with the desktop has slowly been removed from Windows services ("Interact with the desktop"
